What is Optimal Topology Design For Replaceable of Reticulated Shell Based On Sensitivity Analysis about?

The control approach taken is to replace selected bars in reticulated shell structures with passive viscoelastic dampers. A sensitivity method is proposed to determine the optimal topology of dampers. The sensitivities of all structural elements are calculated and compared, considering symmetry, to select the optimal damper locations. Analysis shows the method effectively determines optimal topology, reducing displacement by 5-30% and axial forces by 16-45% under earthquake loading.
